Question 140788This question is from textbook an intermediate course in algebra
: finishing line is rated by pounds of strain at which it is expected to break. If a fishing line is rated at 60 lbs, the line is expected to break if a fish of about 60 lbs pulls at it. in reality, we do not expect all 60lbs lines to breat at exactly 60lbs. one manufacturer sets the specifications for their 60-pound line to have a tolerance of 5 lbs.
a. on a number line, graph the interval for the weights at which the 60-pound line is expected to break.
b. write a compound inequality representing the interval of the weights at which the 60-pound line is expected to break.
c.write an absolute value inequality representing the interval of the weights at which the 60-pound line is expected to break.
please help.thanku

You can put this solution on YOUR website! finishing line is rated by pounds of strain at which it is expected to break. If a fishing line is rated at 60 lbs, the line is expected to break if a fish of about 60 lbs pulls at it. in reality, we do not expect all 60lbs lines to breat at exactly 60lbs. one manufacturer sets the specifications for their 60-pound line to have a tolerance of 5 lbs.
a. on a number line, graph the interval for the weights at which the 60-pound line is expected to break.
Draw a number line
Mark a point "60"
Draw a solid line from 55 to 65
---------------------------------------------------
b. write a compound inequality representing the interval of the weights at which the 60-pound line is expected to break.
55 < x < 65
-----------------------
c.write an absolute value inequality representing the interval of the weights at which the 60-pound line is expected to break.
|x-60| <= 5
====================
